The "B" part number is plastic instead of the rust away metal and it is
slightly larger to seal the hose better. Basically, it is an improved
and upgraded part.

Subject: Rear Heater "T" fitting compatibility

Does anyone know if the late model Vanagon plastic T fitting that taps
into the heater hose to feed the rear heater core will work on an early
'84 Westy?  The part number for the '84 is 353-265-593A.  The late model
number for the same part is 353-265-593B.  I can not seem to find any
source of the "A" part but Van-Caf� sell the "B" part and says on their
web site that it fits '84.  I've looked on ETKA and the spring clips to
attach the hoses to the T fitting are different between  an '84 and late
models which leads me to believe they are different diameter hoses.
However if the hoses are the same diameter I think that the late model T
fitting should work.  My '84 is an early model with metal coolant pipes
running up to the front and the existing T fittings are both made of
"very rusty" metal.  I'm sure I'm not the only one with these rusty
metal T's !

BTW the Bus Depot lists T fitting that I need but I've tried to order it
twice in the past two years and it is always omitted from my order.

Thanks
